I can understand that, for sure. I do think that getting his things out of the house will help your peace of mind, but I realize that you cant really do that at the moment.
Im trying to think of a way that you could open up the dialogue about the birth without blowing your darkness. What if you sent him a text telling him that you wanted him to be there at the meeting so that you could talk to him about how you want him to be there at the birth... ooh, what if that was your boundary. I want you to be at the birth, but I cant have you there if you dont come to the meeting on thursday so that we can talk about it. That way you have set a firm boundary, stated the consequences of breaking it, and told him, clearly, what you want from him.
I guess I gave the wrong finger to the wrong man...
